Effects on Children of Persistent Exposure to Political Violence: Follow-up

说明（由申请人提供）：本申请是一项正在进行的关于接触冲突和暴力对巴勒斯坦和以色列青年心理健康和行为影响的纵向研究的继续提案。三组青少年（最初年龄为8岁、11岁和14岁）每隔一年进行三次评估。对截至2010年6月收集的数据进行的分析表明，遭受种族政治暴力和战争暴力与随后的创伤后应激症状和针对同龄人的攻击有关。当前提案的目标是继续对2010年6月前收集的三波数据进行分析，并再收集一波数据，重点关注年龄较大的队列，因为他们现在已经成年（2013年为20岁），以检查累积暴露于暴力对临床综合征、物质使用、反社会和攻击行为以及支持政治动机暴力的影响。此外，我们将研究与年龄相关的潜在保护因素，这些因素是我们之前没有对这一老年群体进行评估的（例如，公民参与、就业、建设性活动、政治活动和创伤后成长）。我们关注老年群体的动机是认识到，成年早期是一个时期，在这个时期，新的机会和经历给调整带来挑战，而年龄显著的保护因素可能会缓和持续暴露于暴力的影响。然而，对于所有年龄组，我们建议扩展我们对心理健康结果的评估，并扩展我们对情绪反应在应对种族政治暴力中的作用的研究

DESCRIPTION (provided by applicant): The present application is a continuation proposal for an ongoing longitudinal study of the effects of exposure to conflict and violence on the mental health and behavior of Palestinian and Israeli youth. Three cohorts of youth (originally ages 8, 11, and 14) have been assessed three times at one-year intervals. Analyses of the data collected through June 2010 have shown that exposure to ethnic-political and war violence is related to subsequent post-traumatic stress symptoms and aggression directed at peers. The goals of the current proposal are to continue analyses with the three waves of data collected by June 2010 and to collect one more wave of data with a more intense focus on the older cohort as they now reach adulthood (age 20 in 2013) in order to examine effects of cumulative exposure to violence on clinical syndromes, substance use, antisocial and aggressive behavior, and endorsement of politically-motivated violence. Additionally, we will examine age-relevant potential protective factors that we did not previously assess for this older cohort (e.g., civic engagement, employment, constructive activities, political activism, and post traumatic growth). Our focus on the older cohort is motivated by the recognition that early adulthood is a period in which new opportunities and experiences present challenges to adjustment and when age-salient protective factors may moderate the impact of persistent exposure to violence. However, for all age cohorts, we propose to extend our assessment of mental health outcomes and extend our examination of the role of emotional reactivity in response to ethnic-political violence exposure by collecting bio-markers (e.g., cortisol) and assessing skin conductance in response to viewing a video depicting interpersonal violence. This will allow us to test key theoretical propositions concerning mediating cognitive and emotional processes that might account for the long-term effects of violence exposure and distinguish between those highly exposed youth who display more externalizing problems and those who display more internalizing problems.
